9. NENA Development Conference | October 2014 | Orlando, Florida Is a Domain really required?  Yes!  Why can’t I just have a “peer” or “workgroup” style network?

10. NENA Development Conference | October 2014 | Orlando, Florida What other common infrastructure is required?  For managing and monitoring  For protecting and securing  For reliability and availability  For ensuring quality of service

11. NENA Development Conference | October 2014 | Orlando, Florida Security for Next-Generation 9-1-1  Security for Next-Generation 9-1-1 (NG- SEC)  Security is driver for network design  PSAPs must not be the weak link

13. NENA Development Conference | October 2014 | Orlando, Florida Emergency Services IP Network Design for NG9-1-1  OSI Layers 1, 2 and 3  Availability and Reliability  Network Security  Performance  Traffic Engineering and more…

14. NENA Development Conference | October 2014 | Orlando, Florida Supporting PSAP interfaces to the serving ESInet  Application Interfaces drive some underlying network requirements  SIP Call Interface  Additional Data  Management and Monitoring

15. NENA Development Conference | October 2014 | Orlando, Florida Performance requirements  Bandwidth requirements  Media and Metadata  Event and Media Recording  Traffic Prioritization

16. NENA Development Conference | October 2014 | Orlando, Florida Availability and Reliability  What is “five nines”?  How do you achieve five nines?  What’s the difference between Availability and Reliability?  MTBF and MTTR

17. NENA Development Conference | October 2014 | Orlando, Florida Network Management and Monitoring  ESInets must be monitored  Mechanisms for monitoring:  SNMP – v3 vs. v2  Traffic Monitoring  Syslog – what it does  Proprietary mechanisms

18. NENA Development Conference | October 2014 | Orlando, Florida Network Management and Monitoring  Mechanisms for Managing ESInets  As-built documentation  Service Level Agreements  Traffic  Capacity / Trending Analysis  Configuration Management

19. NENA Development Conference | October 2014 | Orlando, Florida PSAP Connectivity (OSI Layer 1)  The Last Mile  Copper, Fiber, RF, Satellite  Reliability and Availability  Redundant and Diverse Paths

20. NENA Development Conference | October 2014 | Orlando, Florida The data link layer (OSI Layer 2)  T1/T3  Frame Relay  ATM  MPLS  Metro Ethernet

21. NENA Development Conference | October 2014 | Orlando, Florida The IP Layer (OSI Layer 3)  Dynamic Routing Protocols  There are choices  OSPF, EIGRP, etc.  The choices drive design requirements

22. NENA Development Conference | October 2014 | Orlando, Florida IPv4 and IPv6  IPv4 is what we’ve seen for years:  179.166.10.1  We’ve run out of public addresses  IPv6 allows for more addresses:  2001:0db8:85a3:0042:1000:8a2e:0370:7334  Build for IPv6 out of the box

23. NENA Development Conference | October 2014 | Orlando, Florida Traffic Engineering  Study your bandwidth requirements  Media consumes a lot – video and audio the most  Text consumes less, but is still significant  Bandwidth and DDOS attacks

24. NENA Development Conference | October 2014 | Orlando, Florida Quality of Service  What is QoS  Why do we need it  What design criteria does it drive?

25. NENA Development Conference | October 2014 | Orlando, Florida Prioritizing network traffic  What is “DiffServ”?  Why does the i3 architecture require it?  What elements must support it?  How does that drive network design?

26. NENA Development Conference | October 2014 | Orlando, Florida What’s special about a PSAP network?  The PSAP network has the same basic requirements as any ESInet – it is an ESInet  But it has a few additional ones, driven by the job a PSAP does

27. NENA Development Conference | October 2014 | Orlando, Florida What’s special about a PSAP network?  The PSAP will likely be connected to other networks that require different, and possibly conflicting network policies  Data services drive these policies (NCIC, LEO DB)  How do we mediate these?  And mitigate risks to disparate networks?

28. NENA Development Conference | October 2014 | Orlando, Florida Policy impact on network design, and vice-versa  How do your policy choices impact the network you design?  How will your network design impact your policy choices?

29. NENA Development Conference | October 2014 | Orlando, Florida The “separate networks” issue  Why do vendors sometimes insist on a separate physical network for their applications?  Why does it matter?  Why is that a problem in NG9-1-1?
